Embodiment Construction

[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0038] At present, the control-by-wire braking system is a brand-new braking mechanism, which is an innovation in the function and touch device of the braking drive mechanism. The control-by-wire braking system cancels the traditional hydraulic braking system, uses the motor to provide the braking energy, and uses the electric signal to transmit the driver's braking intention, and the actuator is an electromechanical brake actuator. When the vehicle brakes, the driver depresses the brake pedal, which has a pedal feel simulator, a...

Abstract

The invention discloses a disc brake and a vehicle with the same. The disc brake comprises the following parts: a clamp body; a linear motor that comprises a primary side and a secondary side, whereinthe primary side is fixedly connected with the clamp body, and the secondary side is provided with a first motor shaft; an electric component configured to selectively lock or release the first motorshaft; and a first brake pad that is arranged on the clamp body in a sliding mode; the first motor shaft is suitable for abutting against the first brake pad, and when the first motor shaft is loosened, the linear motor can drive the first brake pad to move towards a brake disc fixedly arranged on a wheel. Therefore, by adopting the mechano-electronic disc brake, an external hydraulic brake control part is not needed; the structure is compact, the arrangement is convenient, the brake response speed is higher, and the response is more sensitive.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular, to a disc brake and a vehicle having the same. Background technique [0002] In related technologies, the brakes of vehicles mostly use pneumatic or hydraulic brake lines, which have high vehicle quality, delayed braking response, low braking efficiency, and require regular replacement of hydraulic oil. At the same time, there is a risk of hydraulic oil leakage, which is not conducive to Environmental friendly. When the brake is damaged, it is inconvenient to maintain and difficult to disassemble and assemble. The brake pedal produces rebound vibrations during vehicle braking. Moreover, the above-mentioned brake is not suitable for the control-by-wire system, so there is an urgent need to design a disc brake suitable for the control-by-wire system. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior...
